Abstract: 945,859. Aerials. MARCONI CO. Ltd. Dec. 12, 1961 [May 8, 1961], No. 16704/61. Heading H4A. A V.H.F. aerial system comprises at least two reflector elements and a primary radiating element from which said reflectors are spaced by different distances in the direction of, or in a direction parallel to, the direction of maximum gain of the primary element, the reflectors being so positioned, shaped and dimensioned that if the system is transmitting they share equally the energy transmitted and reflect it in a common direction, while if the system is receiving, they receive energy from the common direction and reflect it in substantially equal amounts to the primary element. Preferably, the primary element has its axis directed upwards towards two tilted reflectors. In one such arrangement (Fig. 1) each reflector 2, 3 is planar and is arranged at 45 degrees to the transmission axis. The reflectors are laterally displaced with respect to each other as shown. In an alternative embodiment (Fig. 2, not shown) one of the reflectors is an annulus. The complement of this arrangement is also described (Fig. 3, not shown). In a further embodiment (Fig. 4, not shown) the lower reflector is a semi-transparent mirror, for example a grid of parallel metal rods or a perforated metal plate or a dielectric sheet. The spacing between the reflectors is adjustable is in all cases adjustable.

Abstract: 1,211,984. Sodium carbonate-containing materials. ALLIED CHEMICAL CORP. 31 March, 1969 [4 Sept., 1968], No. 16827/69. Heading C1A. Crystals of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate or sodium carbonate monohydrate are prepared by subjecting a substantially saturated aqueous sodium carbonate and/or bicarbonate-containing process solution to a first evaporative crystallization, separating the crystals from the mother liquor, subjecting this mother liquor to a second evaporative crystallization at a temperature higher than that used in the first crystallization and separating any further crystals from the remaining mother liquor. The process is preferably carried out in a multiple effect crystallization system containing 3 crystallizers, the first crystallization being carried out in the second and third crystallizers, which may be fed in parallel or in series with each other, and the second crystallization being carried out in the first crystallizer, which is fed either from the joint output of the second and third crystallizers if in parallel or from the output of the second crystallizer if in series. The aqueous starting solution is suitably derived from trona and the crystals recovered from the mother liquors may be converted into sodium carbonate.

Title: Improvements in deflection coils for cathode ray tubes
IPC: H01J29/76
Filed: 1939-06-12
Abstract: 530,523. Cathode-ray tubes. TELEFUNKEN GES FUR DRAHTLOSE TELEGRAPHIE. June 12, 1939, No. 17115. Convention date, June 11, 1938. [Class 39 (i)] To reduce coma and astigmatism, a deflecting coil arrangement comprises two crossed coil elements each consisting of one or more turns and embracing a space through which the beam to be deflected is passed. In place of two crossed coil elements, a pair of windings may be used, each of one or more turns and bent so as to be equivalent magnetically to the two crossed elements. Fig. 5 shows a separate pair of crossed coil elements 11, 12 wound on the neck. of a tube 3 in planes which intersect in a line passing through the tube axis, the plane which includes this line and the tube axis being such as to bisect the angle between the intersecting planes. At the crossover points the windings may be flattened, as shown in Fig. 8a, or otherwise arranged to give no swelling of the joint coil thickness. Numbers of turns may be used side by side, so that each element is a solenoid with inclined turns. Fig. 6 shows a form in which separate windings 21, 22, each bent to lie in two winding planes and equivalent to the form shown in Fig. 5, are used. The corners may be sharp, as at 23, or rounded. Ferromagnetic material may be used with the coils, which may, alternatively, be mounted on formers or arranged freely within or in contact with the inner surface of the tube. They may also be used in association with other electromagnetic or electrostatic deflection systems. For deflecting the beam in co-ordinate directions, several pairs of coils may be used, next to or one above each other, and the turns of each coil element may be connected in any predetermined winding scheme. Specification 482,195 is referred to. The Specification as open to inspection under Sect. 91 states that if the angle at which the coil elements intersect is variable, the sensitivity may be thereby controlled. This subject-matter does not appear in the Specification as accepted.
